I don't understand anymore...

First, I installed aMule-2.0.0-1.FC3.i386.rpm, wxGTK-2.4.2-1.i386.rpm, wxGTK-devel-2.4.2-1.i386.rpm, wxBase-2.4.2-1.i586.rpm. aMule was crashing at starting. I installed, desinstalled the rpms multiple times, and it was always crashing.
After that, I installed aMule-2.0.0-1.i386-wxGTK-2.6.0-FC3.rpm with wxGTK-2.6.0-1.i586-FC3.rpm. And it works (I means, I have the GUI), but aMule works well only 5 minutes. After that it hangs (taking 90-100% of the CPU), the GUI doesn't answers anymore. Now, I think I tried 20 times, and each time, same problem.
I haven't changed anything of the linux kernel. I use FC3 as it was first installed.
